Looking for the slowest running 140mm fans I can find

[dmoney1980]

I need 3 or 4 140mm fans, prefer PWM. I would like the start RPM range to be in the 5-600 rpm range. I plan on using 2 of them in the fron intake of my HAF XB Evo case, and possibly two more on my Noctua NH-D14 HSF. I currently have the stock Noctua's on that HSF, but I noticed that the fans seem to get a bit louder as time goes on.

What I'm seeing so far:

Or, would it be better to invest in a fan controller at this point. Thoughts?

Did you look at the Arctic cooling f14's? On sale at newegg currently.

I'm using the f12's in my rigs and they are pretty dang quiet.

Why are you focused on rpm?
Three (four), characteristics should guide you to finding the appropriate 140mm fans for your needs...
RPM, CFM, dB (price)

I have two corsair 140's 1100 rpms ... Quiet edition. Comes with a voltage stepper. Even at full speed they are quiet...

I'll be "too" blunt: Dump those stock Noctua fans! I have become an Akasa Viper advocate, so interesting that's one of your options.

You should be able to run the Vipers at idle at 500 or even lower. I replaced the two D14 Noctuas with one Viper 140R and ducted the cooler to the case exhaust fan behind the cooler.

The round Viper is capable of some ~103 CFM at top-end, or so it is rated. Whatever it is in actual practice, the airflow is "there." At their 1,300 RPM top-end (or maybe it's 1,600), you can "hear" them -- barely -- but they are still "quiet." If you have a simple thermal fan-control strategy, the Vipers will give you greater "range" with less noise.

It depends ultimately on what you're doing and your preferences.

Also, there's a "square" Viper 140mm which certainly does have a top-end of 1,600, and it's capable of 110 CFM or so it's rated.
